PPTP-Client Problem on Mikrotik x86

RouterOS General
1

Hai there,
I have some problem with mikrotik routerOS x86.
Recently i already installed RouterOS 6.35.4 in our brand new server.
All things work except the PPTP-Client.
Before this, our office use mikrotik x86 on VMWare Host, and PPTP-Client connect and working.
I try to backup and restore config file from the old and working router to our new router, but no luck there.
I already try with different tunnel, L2TP and SSTP working as expected.
At PPTP-Client status, stuck on “Link Established”

This is the log from my router ( PPTP-Client - Non Working Router )

Hi,
the problem is Windows related.
Many of my PPTP-servers suddendly (probably all) stop to work with Windows client.
I suppose it’s related with something changed during a Windows Update.
I’m still investigating the problem, anyway the problem is not related to your RouterOS update.

Haii thank you for your reply.
Unfortunately, my setup is mikrotik to mikrotik.

I already try connecting from windows to current mikrotik PPTP Server, and everything working as expected.
